It really depends what kinda mods you gots and whether you have the kind of parts to pass the test, weigh up your options, but keep in mind if you decide to put all your gear into another shell, than your original shell will remain defective and therefore if you try to sell it you must let the buyer know.
To give you an idea, heres a list of what I was failed for:
1. PCV- Venting
2. Charcoal Canister- Not connected
3. General Hoses
4. ITBs- Non-Standard Air Intake
5. ECU- Non-Standard
6. Catalytic Converter- High Flow= FAIL
7. Exhaust Noise- 100db@4950rpm
I've spent just over 1g including labor to pass this shit, and I still haven't passed...Exhaust is too loud still...![]()
